Title: Production of water-soluble polymer particle
Inventor: AMANO TAKASHI
IPC: C08F4/04
Filed: 1983-04-30
Abstract: PURPOSE:To prevent formation of fine particles, to thereby produce a water- soluble polymer of a desired particle diameter and excellent solubility, by effecting the polymerization with the aid of a specified polymerization initiator in carrying out the reversed phase suspension (emulsion) polymerization of a water- soluble monomer. CONSTITUTION:Use is made of a polymerization initiator having a rate constant of decomposition of 0.1X10<-2>-2X10<-2>/min at a temperature which is by 10 deg.C below the azeotropic point of a mixture of water with an organic solvent used, e.g., 2,2'-azobis(2-amidinopropane) dihydrochloride when cyclohexane is used as the organic solvent. Namely, an aqueous solution of a water-soluble unsaturated monomer, e.g., acrylamide, is dispersed in an organic solvent which is immiscible with water but is azeotropically distillable with water in an aqueous solution to organic solvent ratio (by weight) of about 6/4-4/6. The resulting dispersion is polymerized in the presence of the above catalyst at a temperature which is by about 5-20 deg.C below the azeotropic point to a conversion of 10%, and the polymerization is continued under a condition of azeotropic distillation (refluxing accompanied by removal of formed water).

Title: Ic card
Inventor: NAKADA AKIHIKO
IPC: G06F21/79
Filed: 1987-03-30
Abstract: PURPOSE:To protect information stored in an IC card by securing such a mechanism where the IC card does not work before it is detected with a specific optical signal given from an entry system. CONSTITUTION:An IC card 1 is put into an entry system and connected electrically to this system. At this time point, an information protecting device is not valid yet and a central processing part 4 of the card 1 is kept under a halt state. Thus the transfer of data is impossible between the card 1 and the entry system. When a light source 9 of the entry system is turned on, an optical sensor 7 is driven when the coincidence is secured with the wavelength of a filter 6. Then a switch 8 that keeps the part 4 under a halt state is validated and the part 4 works. Thus the transfer of information is possible between the card 1 and the entry system. The wavelength of the filter differs according to its material for production of a BPF, an HPF or an LPF. In such a constitution, the card 1 is available only with a specific system and the protection is enhanced for the information stored in the card 1.

Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain a small DC power supply excellent in heat dissipation by providing a plurality of current detecting elements and a plurality of current supply circuits and distributing the heating elements of the current supply circuit to a heat dissipating means thereby suppressing temperature rise of individual power elements while making uniform the distribution of heat dissipating plates. SOLUTION: A first current flowing through the current detecting element in a first reference current supply circuit 1 is detected as a voltage and employed as the reference voltage of a second current supply circuit 2. Furthermore, voltage of the second current detecting element in a second reference current supply circuit 2 can be fed back to supply a second current proportional to the first current. Similarly, N-th current proportional to the first current can be supplied to an N-th current supply circuit. Since a required load current can be supplied while being distributed, heating elements can be arranged while being distributed. Furthermore, ratio of currents flowing through the current supply circuits can be set arbitrarily by regulating current detecting elements R1, R2, R3 arranged in the current supply circuits while being distributed.
